As shown in FIGS. 1 to 6, an easy use and light weight closure frame on luggage includes a casing shell 1, a middle frame 3, an inner lining, and a clamping piece. The casing shell 1 includes a first casing shell 2 and a second casing shell 6. The middle frame 3 includes a first middle frame 4 and a second middle frame 5. The clamping piece includes a first clamping piece 12 and a second clamping piece 20. An upwardly protruding connecting member 9 is provided on the first middle frame 4, and a connecting groove 8 is provided on the second middle frame 5 for engaging with the connecting member 9. The connecting member 9 is inserted into the connecting groove 8 so that the first middle frame 4 and the second middle frame 5 are closed.

An outer side of the first middle frame 4 is provided with a first casing shell clamping slot 10 oriented downwards, and an outer side of the second middle frame 5 is provided with a second casing shell clamping slot 7 oriented upwards for respectively mounting the first casing shell 2 and the second casing shell 6. The first casing shell 2 and the second casing shell 6 are respectively inserted into the first casing shell clamping slot 10 and the second casing shell clamping slot 7, and are respectively fixedly connected to the first casing shell clamping slot 10 and the second casing shell clamping slot 7 by means of adhesive bonding.

An inner side of the first middle frame 4 is provided with a first inner clamping slot 15 having an upward opening. The first inner clamping slot 15 is disposed around the inner side of the first middle frame 4, and the first inner clamping slot 15 is provided with an oblique-wedge-shaped first elastic piece 14. The first elastic piece 14 is inclined toward an inner side of the first inner clamping slot 15 and has a hollow structure. One end of the first elastic piece 14 is fixed to an upper end of a first side wall 16 of the first inner clamping slot 15, and the other side is freely to suspend downwardly. The first elastic piece 14 is provided in plurality and distributed around the first middle frame 4.

An inner side of the second middle frame 5 is provided with a second inner clamping slot 18 having a downward opening, and the second inner clamping slot 18 is disposed around the inner side of the second middle frame 5. The second inner clamping slot 18 is provided with an oblique-wedge-shaped second elastic piece 19. The second elastic piece 19 is inclined toward an inner side of the second inner clamping slot 18 and has a hollow structure. One end of the second elastic piece 19 is fixed to an upper end of a second side wall 17 of the second inner clamping slot 18, and the other side is freely to suspend upwardly. The second elastic piece 19 is provided in plurality and distributed around the second middle frame 5.

For the lightweight design of the first middle frame 4 and the second middle frame 5, the first elastic piece 14 and the second elastic piece 19 are configured to be a hollow structure, which reduces the weight of the casing body without affecting the performance.
